Re: [Orgmode] Pretty org-entities in org-mode buffers

Hi Carsten,
This appears to be an issue in the HEAD (as of two weeks ago) of the

Emacs git repository. I was able to get around this issue (and a
couple
of other font-lock related issues) by stepping back to an older
version

of Emacs (tag EMACS_23_2 in the git repository).
I haven't tried to go back to the Emacs development HEAD, but I assume
that they'll take care of this issue sooner or later, either way it's
not a problem with any of the code in Org-mode.

OK, thanks.

I actually did pull the latest git mirror, and I did not see any
problems....

have you been able to get past this issue?

So looking into this slightly deeper,
I do have org-pretty-entities set to t in my config.
Toggling entities display with C-c C-x \ has no effect.
The value of org-highlight-latex-fragments-and-specials is nil.
Entities are only displayed when I search for the "\\" character, no
other searches result in displayed entities.

I have the same problem, so maybe my version of Emacs is to blame,
I'm

using the latest from the emacs git/bzr repo

Hi Carsten,
Thanks for folding in this feature.
I'm having some weird issues using the new entities display. The

entities are not fontified in my org-mode buffers despite having
set

the
org-pretty-entities variable to t. However if I search
`isearch-forward-regexp' for the "\\" character in the buffer then
all
of the entities are displayed (e.g. \sum is replaced with ∑).
Any idea why the entity display is only working during a search?

One idea: Do you have turned on org-highlight-latex-fragments-and-
specials?

Hi everyone,

a modified version of Eric's code is now included into Org, I
just

pushed it
to the git repo.
You can use the command `C-c C-x \' to toggle this feature.

The variable `org-pretty-entities' determines if this mode is
on by

default.
Finally, you can use
#+STARTUP: entitiespretty
#+STARTUP: entitiesplain
to change things on a per-file base.
Thanks to Eric for this great idea.

Hi,
Recently I've been making use of org-entites for exporting my
greek/
math
heavy class notes to HTML. I'm really loving the results.
This morning I've started playing around with the below function
`org-pretty-entities', which is adapted from Phil Hagelberg's

`pretty-lambdas'[1]. Calling this function in an org-mode
buffer

will

have the effect of fontifying all org-entities text strings as
the

character which they represent, so \Delta is replaced with Δ,
\lambda
with λ, \in with ∈, and so forth.
I've just started playing with this, and I make no guarantees as
to
it's
safety or utility, but I was very pleasantly surprised by the
simplicity
of the function, and how nice it's been to see my special
characters
appear in org-mode buffers as I type.
